Planting techniques of Cherry Blossom trees

Cherry blossoms are native to the temperate Himalayas in the northern hemisphere. they grow all over the world and can be divided into two categories: single and double. Single-petal can blossom and bear fruit, while double-petal usually does not bear fruit. The flowers often blossom with or after leaves in March. The flowers are fragrant and colorful and are often used in gardens. Let's take a look at the planting techniques of cherry trees.

Growth habits of cherry trees

Cherry blossoms are temperate and subtropical tree species, which are sexually fond of sunshine and warm and humid climatic conditions, and have a certain ability to resist cold. The requirement of soil is not strict, it is suitable to grow in loose, fertile and well-drained sandy loam, but it is not resistant to saline-alkali soil. The root system is shallow, avoid stagnant water low-lying land. It has a certain degree of cold and drought resistance, but it is weak against smoke and wind, so it is not suitable to plant coastal areas with typhoons.

Propagation methods of Cherry Blossom trees

1. Sowing and propagation: the seeds of fruiting cherry blossoms are sown after harvest. When cultivating cherry blossoms by sowing, care should be taken not to dry the seed embryos, but should be sowed in the spring after picking or wet sand accumulation, so as to cultivate seedlings for grafting.

2. Cutting propagation: the cuttage propagation of cherry trees usually uses one-year hardwood in spring and tender twigs in summer. Cuttings can be treated with NAA, and the seedling bed needs a medium with good shading, moisturizing and ventilation to have a high survival rate.

3. Grafting propagation: because most species of cherry blossoms will not bear fruit, cherry or mountain cherry can be used as standing trees for grafting, either cutting in late March or budding in late August, and can be planted in the nursery after 3-4 years of cultivation. It can also be grafted instead of branches, and the chopped scion can be inserted into the rootstock by split grafting, wrapped with plastic bags and covered with plastic bags for heat preservation and protection, and the survival rate can be used to replace new varieties.

Planting techniques of Cherry Blossom trees

1. Dig holes for planting: the cherry trees should level the ground before planting. A hole with a diameter of 0.8 meters and a depth of 0.6 meters can be dug. The pit is first filled with 10 centimeters of organic fertilizer, and the seedlings are put into the pit so that the roots of the seedlings extend in all directions. After filling the soil, lift the seedling up to make the root spread deep, and then do it firmly. The planting depth is about 5 cm from the upper layer of the seedling root. water it after planting, fully irrigate it, and set it up with a stick to prevent it from being blown down by strong winds.

2. Rational watering: the seedlings of cherry trees are vulnerable to drought after planting. In addition to full irrigation during planting, they should be irrigated once in the next 8-10 days to keep the soil moist but without stagnant water. Loosen the soil in time after irrigation, it is best to cover the surface thinly with grass to reduce water evaporation. Within 2-3 years after planting, in order to prevent the trunk from drying, it can be wrapped with straw. However, after 2 to 3 years, the seedlings grow new roots and gradually increase their adaptability to the environment, so it is no longer necessary to cover grass.

3. Timely fertilization: Cherry blossoms are fertilized twice a year, and acid fertilizer is better. One is winter fertilizer, and organic fertilizer such as bean cake, chicken manure and mature fertilizer is applied in winter or early spring. Another time after falling flowers, ammonium sulfate, ferrous sulfate, calcium superphosphate and other quick-acting fertilizers were applied. In general, the method of hole application can be adopted for the fertilization of large cherry blossom trees, that is, digging a circular ditch with a depth of about 10 cm at the edge of the positive projection line of the crown, applying fertilizer, which is not only simple and beneficial to root absorption, but also increases with the growth of the tree. The diameter and depth of the ring ditch of fertilization also increased.

4. Reasonable pruning: pruning is mainly to cut off withered branches, overgrown branches, overlapping branches and disease and insect branches. in general, when many branches grow on the trunk of large cherry blossoms, some strong branches should be retained, and the rest should be cut off from the base to facilitate ventilation and light transmission. The pruned branches should disinfect the wound with medicine in time to prevent the invasion of bacteria after rain, resulting in decay. Cherry blossoms after a long period of sun exposure, the bark is easy to aging damage, resulting in decay, it should be removed in time and disinfection treatment.

5. pest control: Cherry blossoms mainly have two kinds of diseases: glue flow and root rot, which should be treated and improved in time, water and fertilizer management should be strengthened, and reasonable pruning should be done. During the growth of cherry blossoms, aphids, red spiders and shell insects will occur in a year, generally spraying 3-4 times, the first in the early flowering, the second in the late flowering, and the third from July to August. It is necessary to observe carefully and prevent in time in order to achieve better results.
